Sorry to enter this topic without an answer, but what I'm trying to simulate is something similar (well not so extreme).

I have a plastic part inflected by 1 mm over a 500mm length (the deformation could be simplified in an arc) and I'm looking if a can make it straight fixing a thin metal plate with 2 screws on the curved face of such plastic part.

The deformation is within the elastic field as I have a real part as a reference that behave in this way.

I am wondering how to handle the forced displacement on one component and how to transfer that displacement as it become the internal tension in the metal plate.

Basically what the poster is trying to achieve: deform a component with another making different shaped faces coincident at the end of the process (sorry for the oversimplification)
